Finding Water Is Not the Same as Building a Supply

A resource needs an address

The statement that the Moon has water sounds like a solution. For a mission designer, it opens a list of questions. Where is the water? In what form? At what concentration and depth? How much material must be moved to recover it, and what equipment can survive at that location? A discovery becomes operationally useful only when those questions have sufficiently dependable answers.

NASA's account of lunar water describes several lines of evidence, including observations of material ejected by the LCROSS impact and detections in permanently shadowed regions. These findings establish a scientifically important presence. They do not describe a uniform underground reservoir available wherever a future crew chooses to land. The local conditions still determine the extraction problem.
